Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy.

Introducing The Paleo Primer: A Second Helping

It’s been busy this year with the release of several new books, but there’s one that’s been under the radar that I think you’ll be especially excited about. Remember in 2013 when I published The Paleo Primer by Keris Marsden and Matt Whitmore? This delightful book introduced us to paleo/primal principles in the wittiest of ways, and then dished out creatively delicious primal recipes. Well with your help it went on to enjoy global success with copies published in the UK (Ebury Publishing) and Germany (Goldmann Verlag), and it’s ranked #1 in many categories on Amazon, including Paleo Diet, Low-Carb Cooking, and Exercise and Fitness. Thankfully, Keris and Matt weren’t done, and they’ve spent the last three years perfecting even more mouthwatering, primal-approved meals. And we’ve packaged them all together in The Paleo Primer: A Second Helping!
